MECHANICAL MOVEMENT.

To all whom it may concern:

Be it known that I, CLARENCE E. WRIGHT, a citizen of the United States, residing at Louisville, in the county of Jefferson and State of Kentucky, have invented a new and useful Mechanical Movement, of which the following is a specification.

This invention relates to an improved mechanical movement, and has for an object the production of a movement wherein a driving member will rotate a driven member one fourth of a turn during a portion of its revolution and hold it rigidly against movement during the balance of the revolution.

With this and other objects in view the invention consists of the novel arrangement, and construction set forth, and illustrated in the accompanying drawing which forms a part of this specification, in which is set forth an embodiment of the invention, but it is to be understood that changes, variations and modifications may be resorted to that come within the scope of the appended claims.

In the drawing, in which like reference characters indicate like parts in the different views; Figure 1, is a front elevation of the movement; Fig. 2, a side elevation; Fig. 3, a rear elevation, partly in section; Fig. 4:, a plan view of the driven member; Figs. 5, 6, 7 and 8, are diagrammatic plans. showing the movement of the driven member.

Referring to the drawings, 1 indicates the driving member, an oblate spheroid, secured on a shaft 2, that may be mounted in bearings of a suitable nature such as 3. Any suitable means may be employed to revolve the driving member, but I have illustrated a crank, 1. Two rings, 6 and 7 are arranged circumferentially of the spheroid, and are spaced apart to form a central channel, or path, 8. A portion of the ring 6 is cut away and a guide piece, 9, is so positioned as to form passages, 10 and 11, communicating with the channel 8. Passages, 12 and 13, are formed through the ring 7 The sides of the rings and the pas- The driven member, 15, is a disk secured on the end of a shaft, 16, that is mounted in suitable bearings, 17 The face of the driving mem- Specification of Letters Patent.

ber 17 is concave and is adapted to bear against the face of the driving member 1.. Extending from the face of the disk are a plurality of pins adapted to engage with the driving member. A central pin, 18,permanently engaging the channel 8. Pins 19, 20, 21 and 22 are arranged equidistant around a circle of such diameter that diametrically opposite pins will bear against the outside walls of the rings 6 and 7. The pins 19, 20, 21 and 22 extend from the concave surface of the disk on lines radial to the center of the driving member, said pins are removably secured in the disk by means of set screws 23.

During a major portion of a revolution of the driving member diametrically opposite pins (as 19 and 22 in Fig. 8) are engaged in the channel 8, and no movement of the driven member is possible. As the driving member turns in the direction of the arrow (Fig. 1) the guide piece 9 strikes a pin 19 (Fig. 5), at this moment the pins 19, 20 and 21 are opposite the openings of the passages 10, 11 and 12 respectively, and the driven member may be rotated by the action of the inclined side of the guide piece 9 on the pin 19, the pin 19 riding up through the passage 10, the pins 20 and 21 entering the passages 10 and 11 respectively; as the movement continues the pin 22 enters the passage 13. When the pin 19 reaches the apex of the guide piece 9, the driven member will have received a quarter turn, the pins 19 and 22 will be in the channel 8, and the pins 20 and 21 bearing respectively against the outside of rings 6 and 7, this arrangement holding the driven member against movement until, with the completion of the revolution of the driving member, the guide piece strikes the pin 20 when the foregoing sequence of movements will be repeated, the driven member receiving a quarter turn at each revolution of the driving member. As in course of the rotative motion of the driven member the pins that pass through the passages 10 and 13 come in contact with the inner walls of the rings 7 and 6, it is evident that no overthrow is possible. And that the pin bearing against the outside of ring 6 prevents any rebound.

Having described my invention so that member having a concave face to bear' against the driving member, pins extending from the driven member and engagingioneach side of said rings, and a guide piece on the driving member to guide the pins through said passages.

2. In a mechanical movement, a driving Wheelhaving a convex face, a-driven' member having a concave face to bear against the driving Wheel, pins extending from the driven member, the driving Wheelprovided with paths for said pins, and With p'assages connecting said paths, and a guide piece located in one of said paths to guide the pins through said passages and to rotate said driven member.

3. A driving member provided With circumferential'paths on the periphery thereof, and with passages connecting said paths, adriven member provided With a face contoured to conform to the periphery of the driving, member, pins extending from the face of the driven member andadapted to enter saidpath s, anda guide piece located in one of said paths to guide the pins through said passages and rotatethe' driven member;
